network commands no response.

dear guruys,

this is just to let u know i build a new machine that has gateway
internet proxy enabled to go outside world.

and i can run internet there using firefox and mozilla etc work fine

now when i try to run some test of telnet,host,dig,nslookup,traceroute
it return me below error, can any one advise what things to be check
missing or anything to install further to this. be advise and what
files on slackware linux workaround.

however the local lan same commands r working, but outside world they
did not work.

we allowed from firewall only port 110,25,443,8080,80 to go outside,
it wil be email server

Are you trying to configure your own DNS server running on this machine?

You are obviously not able to reach your DNS servers, so which DNS servers
to you try to reach?

cat /etc/resolv.conf

Does your machine have a static IP address or is it assigned with DHCP?
Normally when DHCP is used DHCP is also responsible for telling which DNS
servers to use. If you use static IP adress you should know the IP
adresses of your DNS servers as well as other IP settings like IP address,
gateway and netmask.

As said, your DNS is misconfigured and you are unable to look up any IP
adresses. You might be able to do:

telnet 64.57.102.34 80

The above will work assuming that you have configured your IP adress and
routing correctly.

Re: network commands no response.

Dear Henrik and Gurus,

Thanks for so prompt response and help appreciated.

- Yes I am you trying to configure my own DNS server running on this
machine?
- it is static ip address, with gateway,subnet mask defined already
- internet is live on this machinee, from the web/internet i can see
the address like http://mail.go.com, and on firewall also
pop,smtp,dns,proxy,8080,https,443 ports r kept open
- i try to define the resolve.conf, where it shows like
cat /etc/resolv.conf
========================================
search go.com
nameserver 64.64.10.10
nameserver 192.192.192.10
========================================
- it looks like my dns is misconfigured or not properly configured,
however if i run the test outside world like pop,smtp,proxy it work
fine, but the mail problem with dns configuration within the machine.
- the ip has taken from one of the isp, and we also request them to
insert the reverse entry
- basically it will be a email server like qmail,and we want to make
as testing full blown server

your tips help guideline will be highly appreciated.

thanks and kind regards
salim

Configuring bind is a non trivial task. Do you really need your own DNS
server? It would probably be much easier if you could use the DNS servers
from your ISP.

If you still want to configure your own DNS server, which client machines
will it serve? Will only your own machines in your network use this DNS
server or will you be serving the entire internet?

Which hostnames will this DNS server serve? Will it only server the names
of your own hosts in your internal network or will it also serve host
names from the internet?

In your resolv.conf you have two different DNS servers. As your name
lookups fail totally we can assume that none of them are working. I
suppose that one of those IP addresses is the address of your slackware
machine? What is the other IP address, did you also try to configure that
DNS server yourself?

I think that a first step to get a working mail server would be to find an
existing working DNS server and use that. Next, if you really want to
setup a DNS server of your own you have two choices. Either you read up on
how to configure bind. Maybe the book
at http://www.oreilly.com/catalog/dns5/ is a good start. Or, if you want
to keep things as simple as possible there might be a shortcut:
